Claymore is good. The Mura is excellent. Halberds will also fair pretty well. You can just go through mugen looking at stuff but remember, its moveset not damage thats most important.

I Built a 40/40 toon the other day, has been a great deal of fun, really awesome. I discovered the amazing great scythe, I found the moveset and damage to be quite incredible. Def worth checking out. And yah, claymore is good for scaling, amazing moveset aswell.

Don't count out the Sunlight Straight Sword, Balder Side Sword or Pike. I use them a lot on my 40/40. The Bastard Sword also beats the Claymore for me. I tend to avoid the slower weapons on a 40/40 though because you won't have a whole lot of Vit (if like me you have more End to carry 3 weapons and a shield) and slow weapons are too easy to parry/avoid/punish.

The Great Scythe is also beast, but learn to play locked-off and expect a lot of roll backstabs

The Washing Pole beats out the Uchi's scaling at 40/40 and actually deals better damage with more range. I second the DSS for its range, but I've found the Pike beats it in terms of damage at 40/40 and +15, especially if one has no faith.
